Abstract
Background: Hemorrhoidectomy is the basis of treatment for grades three and four hemorrhoid. One of the major post hemorrhoidectomy problems is pain that is usually due to the spasm of the internal sphincter. There are different methods for the management of postoperative hemorrhoidectomy pain. The aim of this study was to investigate the effect of sphincterotomy on post hemorrhoidectomy pain.
Materials and Methods: This interventional clinical trial was conducted on 60 patients with 3rd and 4th grade hemorrhoid who had randomly been divided into hemorrhoidectomy and hemorrhoidectomy combined with sphincterotomy groups. The degree of pain was measured on visual analogue scale (VAS) and analyzed through Mann-Whitney, Friedman, and Chi square tests via SPSS version 14.
Results: In terms of reduction in pain with sphincterotomy, there was a significant relationship between the two groups on the first, second, and fifth postoperative days (P=0.001). On the third and sixth postoperative days, a significant relationship was observed between the two groups (P=0.001). Days four and seven also indicated a significant relationship between the two groups (P=0.002). However, there were not any significant relationships between the two groups in terms of urinary and fecal incontinence and gas retention (P>0.05). A significant relationship existed between the two groups in terms of reduction in the need for sedation (P=0.006).
Conclusion: Lateral internal sphincterotomy combined with hemorrhoidectomy can reduce the patients’ post hemorrhoidectomy pain and can reduce the use of analgesics, but it does not have any significant influences on the incidence of urinary retention and bleeding after the first defecation and does not increase the risk of fecal and gas incontinence in comparison with the hemorrhoidectomy group.

Abstract
Background and Aim: Extensive prevalence of myocardial infraction, and an increase of 36% in total deaths due to it by 2020, and attention to the causes and methods of alternative therapy is very important. There are different ways in treating these patients that endurance training is one of them. The aim of this study was to evaluate the effect of 8 weeks of incremental endurance training on serum levels of TSP-1 and MMP-1 in male Wistar rats with myocardial infarction.
Materials and Methods: In this controled experimental study with control group, 20 rats weighing 230 ±30 g (8-week-old) were randomly divided into incremental endurance training and control, after induction of infarction with Isoproteronol (150 mg/kg). The training group performed an 8-week training session (3 sessions a week, for 20 to 50 minutes at 12 to 18 meters per minute).Then, 24 hours later, the venous blood sample was collected to evaluate serum concentrations of TSP-1 and MMP-1 and transferred to the laboratory. Independent t-test was used to analyze the data at a significant level of p <0.05 to Graphed Pad software.
Ethical Considerations: This study with research ethics code IR.IAU.ARAK.REC.1397.007 was approved in Research Ethics Committee of Islamic Azad University, Arak branch, Iran.
Findings: The results showed that endurance training significantly increased serum MMP1 levels (p = 0.048) in rats with myocardial infraction, while there was no significant effect (p = 0.092) on the exercise program in serum TSP-1 levels.
Conclusion: the result of this study suggests that increasing endurance training may increase MMP-1 in rats with myocardial infraction, which can play an important role in angiogenesis and replacement of capillaries.
